Properties

Directions for use

• Dilution: Suitable solvents are ethyl acetate (EA),  Methylethylketone provided that the water content does not exceed 300 ppm. Do not use aromatic or alcoholic solvents.
• Preparation of Adhesive Mixture: After having added the right quantity of solvent to 776A and having achieved t the required solid content, 776B has to be stirred into the 776A solvent mixture.

List of Dilution: When the ethyl acetate is used for dilution to obtain an accurate solid content, the amount required should refer to the following table

* Viscosity is based on the average viscosity of the Ford cup 3# (25°C).

• Pot life: The ready-for-use adhesive in closed containers has a working time of about 24 hours. If the laminating machine doesn’t use up adhesive, the retention time shouldn’t be more than 2 hours. Otherwise, the adhesive should be abandoned, or it may result in unstable laminated film.

Tropical area (Temperature >28°C + humidity >60%) pot life: Ready-for-use adhesive should be used up within 2 hours.

• Coating: 776 is suitable for dry film laminating machine with smooth roller or gravure roller. Before mass production, repeated trials should be carried out to determine fitting roller.
• Coating weight: Depending on the film or foil combination and the end use of the laminate, the adhesive weight may range from 2.0-3.5g/m² (dry). For printed laminates the weight has to be adjusted accordingly, it should be approx.0.5-1g/m² higher than for unprinted films.
• Dry: The laminating machine should have good air volume, wind speed, wind pressure and the appropriate temperature to avoid residual solvents. Temperature setting generally follows gradient principle (55°C-65°C, 65°C-75°C, 70°C-85°C). Adjust the temperature of the oven according to the performance of the processed products, raw materials, processing technology.
• Pressure adjustment: An appropriate increase in laminating temperature and pressure can improve the bonding strength and surface finish of the laminates.
• Curing: Stored in curing chamber (35-45°C) or similar wild enviromnent, various film/film and film/foil the laminates will be ready for cutting within around 24 h. Nevertheness, the curing time should be extended if the laminates are used for bagging.

TDS Weeton 819A 819B EN.pdf

Weeton 819A/819B is a cost-effective two-component solvent-free flexible packaging laminating adhesive is widely used to laminate between transparent film and aluminized films. The product can be used in food, medicine, daily chemicals, and industrial packaging materials.

819A/hardener 819B two-component solvent-free adhesive has low viscosity and excellent wetting performance, which meets the requirements of high-speed laminating (350 - 400 m / min). Suitable for different materials including plastic-plastic, aluminized, aluminum-plastic, and other composite material structures. 819A/ hardener 819B does not affect the openness of the inner layer of the composite film, does not contain castor oil components, the adhesive layer is transparent after curing, odorless, elastic, and resistant to aging. 819 A/ hardener 819 B provides an ideal pot life, faster-curing speed, and good peel fastness.

The typical applicable structure is as follows +:

• OPP (PET) / met. CPP
• BOPP / met. CPP (met. PET) / PE
• OPP (PET) / CPP ( PE)
• Nylon / LLDPE(CPP)
• PET(OPP) / PE (CPP)

+: Film should get appropriate surface tension by corona treatment

Properties

* Mass ratio changes from 100: 55 to 100: 65 depending on the humidity and films.

Directions for use

• Ratio: The standard mass ratio 819A/hardener 819B = 100: 60 can be fine-tuned according to the properties of the product, the ink, the packaging material, and the operating conditions.
• Mix method: Mix by automatic mixing machine, mix evenly before use.
• Coating system temperature setting: Recommended mixing and coating operating temperature parameters are shown in the "Typical Use Parameters column" and can be adjusted according to the actual conditions of use.
• Coating: Suitable for specialized laminating equipment with multi-roll coating systems.
• Coating weight: Depending on the combination of plastic film or aluminum foil and the end use of the laminated film, the coating amount of the adhesive can range from 1.2 to 3.5 g / m². Usually, for printed film lamination, the coating amount needs to be increased appropriately.
• Adding: Use a two-component dosing and mixing unit to add the adhesive continuously to the adhesive tank of the solvent-free laminator. The adhesive in the tank should be kept as fresh as possible to avoid abnormal viscosity affecting the coating result.
• Pot life: 819A/Hardener 819B component has a pot life of about 60 minutes at 45°C after mixing and shows reliable workability. See Figure 1 below.
• Laminating conditions: Precise tension control and proper winding procedures prevent delamination, roll head size difference, and film curl.
• Curing: Cure at 35 - 45℃ for 1-2 days for rewinding and slitting. For three-layer laminates, the second layer of raw material is laminated and then cured for 12 hours before the third layer is laminated. Laminates are usually cured at 35- 45℃ for 24 hours, normal products are stored at room temperature for 3-5 days to fully cure.
• Cleaning: When the machine is shut down for more than 30 minutes, the metering roll position adhesive can no longer be used and the coating unit needs to be cleaned with a solvent/plasticizer mixture (refer to Safety Precautions). The two-roller coating unit also needs to be cleaned and the same cleaning procedure should be carried out at the end of the start-up period.
• Bonding data performance test: in a variety of plastic/plastic, plastic/aluminum composite processes, it shows excellent bonding performance.
